I think there is one for sale here in Arizona. It was a mint, low-mile little old lady Sun City Arizona wagon with a 305 4bbl. A Super Class racer bought it thinking he could perform a Stocker transformation just by adding headers, cam, valve job and convertor / gears. Boy was he wrong. Imagine that...So then he got serious about it and last I heard it was good for 3-4 under, maybe worse. I think he wants $7500 for it. I might be wrong though. E-mail me if your interested and I'll track him down.
